Abstract
Classical molecular dynamics (MD) is used to study vibrational relaxation a nd predissociation processes in I-2 embedded in a rare-gas environment. It is shown that the simultaneous effect of the two mechanisms determines the deviation of experimental pump-probe signals from a single-exponential deca y [Lienau and Zewail, J. Phys.
